Version 8 of the Equallogic PS firmware introduces a default policy for automatic snapshot creation. This means that by default, a daily snapshot will be created for each volume present in the group. The policy also states to keep 2 snapshots, which can be very space consuming, quickly filling up your Equallogic.

When upgrading the firmware to version 8 from an earlier version, this policy will automatically be created and activated, without telling you, causing headaches among those unaware of this change.
